Abstract in simplified Chinese:揭示一种主光罩支撑机构,其中一主光罩可快速且轻易的设置与卸下,且其能够稳固的支撑一主光罩,用以存储与输送。本发明之一较佳之实施例包括一对主光罩支撑件,固定于该容器之一门上,以及一对主光罩保留器固定于该容器之一外壳上。当该容器外壳于该容器门相联结时,该主光罩支撑件及该主光罩保持器之部分啮合该主光罩之斜角边缘,且将该主光罩夹在该容器中之一固定的位置上。结果于其斜角边缘啮合的该主光罩,可以避免与该主光罩之上部及下部表面以及垂直边缘的可能有害接触。
Abstract:
A variable lot size load port assembly includes a tool interface, an advance plate, and a seal plate. The tool interface extends generally in a vertical dimension and has a front surface, a back surface generally parallel to the front surface, and an aperture. An advance plate is positioned to the front of the tool interface below the aperture. The advance plate extends generally horizontally and is configured to support a front opening unified pod (FOUP). The advance plate translates between a retracted position and an advanced position. The advanced position is proximate the tool interface and the retracted position is spaced from the tool interface. The seal plate has an upper end secured to the tool interface and a lower end covering a portion of the aperture to form a reduced aperture. The seal plate is shaped to form a proximity seal with a front flange of a FOUP of a selected capacity mounted to the advance plate and brought to the advanced position.
Abstract:
The present invention comprises a stocker for managing containers within a fabrication facility having a ceiling-based interbay material handling system a floor-based intrabay material handling system. In one embodiment, the stocker comprises a container storage area for storing at least one container, a ceiling-based input conveyor, a floor- based conveyor and a robotic mechanism. The ceiling-based input conveyor receives containers from the ceiling based interbay material handling system. The stocker' s floor- based conveyor may comprise an output conveyor, an input conveyor or both, and moves containers between the stocker' s container storage area and the floor-based intrabay material handling system. A robotic mechanism moves containers between the ceiling- based input conveyor, the container storage area and the floor-based conveyor.
Abstract:
The present invention generally comprises an apparatus for transporting containers between a first transport system and a second transport system. In one embodiment, the first transport system comprises a ceiling-based conveyor and the second transport system comprises a floor-based conveyor. The present invention may further include storage shelves, preferably substantially horizontally aligned about a common vertical plane with a section of one of the transport systems. The transport system may be located either directly above the uppermost storage shelf or beneath the lowermost storage shelf in order to add storage capacity within the fab. A vertical module transports containers between the transport systems and the at least one storage shelf.
Abstract:
A system for preventing contaminants and particulates from coming into contact with a back side of a workpiece as the workpiece is vacuum held on a chuck or robotic end effector.
Abstract:
A cassette support and rotation assembly (100) for receiving wafer-carrying cassette (113) through a SMIF port and thereafter orienting the cassette to a desired rotational position with respect to a processing station (103) on or in which the cassette is located. The cassette support and rotation assembly according to embodiments of the invention includes a port door (104) for receiving a SMIF pod door (112) and a wafer-carrying cassette supported on the pod door. The assembly further includes elevator (105) to which the port door is rotationally mounted by means of bearings (124a-c) provided around a lower surface of the port door. In embodiments of the invention, the cassette support and rotation assembly further includes a rotation drive mechanism (132) on a lower surface of the port door for controllably rotating the port door with respect to the elevator so as to align the cassette on the top surface of the port door to the desired rotational orientation.
Abstract:
An adaptor plate (100) for allowing 200 mm SMIF pods (112) carrying one or more semiconductor wafers to be used on an access port (108, 110) of a wafer processing station configured to accept a 300 mm SMIF pod. The adaptor plate (100) has a substantially circular outer circumference conforming substantially in size and shape to the outer circumference of a conventional 300 mm SMIF pod, and a central opening (102) conforming substantially in size and shape to a conventional rectangular 200 mm SMIF pod (112). The one or more semiconductor wafers are supported on pod door (116) of the pod (112), and the semiconductor wafers and pod door (116) are lowered through the central opening (102) in the adaptor plate (100) into the wafer processing station. With the adaptor plate (100) supported on the access port (108, 110), and a cover (114) of the 200 mm SMIF pod supported around the central opening (102), the access port (108, 110) is entirely covered and entry of contaminants into the processing station through the access port (108, 110) is prevented.
